The Ted Cruz campaign is hitting back after Donald Trump called for a "new election" after alleging that the Texas senator "stole" the Iowa Republican caucus.

Trump came in second to Cruz in Iowa Monday night. The billionaire businessman was uncharacteristically silent on Twitter through Monday night and much of Tuesday, but early Wednesday morning he launched into a Twitter tirade in which he accused Cruz of "fraud."

"That is why all of the polls were so wrong and why he got far more votes than anticipated," Trump tweeted.

Cruz's communication's director, Rick Tyler, later fired back at Trump in a statement, saying that "reality just hit the reality star."

"[Trump] lost Iowa and now nobody is talking about him, so he’s popping off on Twitter," Tyler wrote in an email to Politico. "There are support groups for Twitter addiction, perhaps he should find his local chapter."
